Blank Heatmaps in GLMakie

Hi @sdanisch. I’ve just removed 0.3.0 and added 0.2.9 and the heatmap seems to work OK.

Ok…
Since there is no obvious problem with the heatmap shader and no errors, I don’t have much to play around with

I tried to clean up the shaders a bit and double checked that all variables are initialized correctly - there is some small hope, that this may fix the problem:

If anyone can try out that branch, it would be great to know if that helped!

That seems to have fixed it. Thanks so much! I’ve been relying on Julia/GLMakie for streaming and displaying acoustic data from an ADC/FPGA.
